The discharging opening in portion, is additionally provided with final drive shaft in the casing, be provided with blade on the final drive shaft, the final drive shaft with
Decelerator is connected, and the decelerator is connected with motor, is also arranged at including two symmetrical on the wall of the feeding cylinder side
Material spraying hole, the axis of the feeding cylinder is mutually perpendicular to the axis of the material spraying hole, two material spraying holes respectively with two
Pneumatic conveyer is connected, and the internal diameter of the feeding cylinder is 5cm to 10cm.
Further, the angle formed by the axis of described two material spraying holes is 120 ° to ° 150 °.
Further, constant feeder is provided with the Pneumatic conveyer.
Further, the Pneumatic conveyer is storehouse pump.
Further, the Pneumatic conveyer is material envelope pump.
The invention has the beneficial effects as follows：Combustion adjuvant powder and coal dust can collide in feeding cylinder mixing, in pan feeding
In the middle of process, with the continuous injection of combustion adjuvant powder and coal dust, the state of constantly mixing is kept, fall into blender afterwards again and work as
In, the effect full and uniform so as to reach mixing.

Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples, as shown in figure 1, a kind of coal dust mixing of the invention
Blender, including support 1, are provided with casing 2 on the support 1, the casing 2 also includes being arranged at the top of the casing 2
Feeding cylinder 3 and the discharging opening 4 for being arranged at 2 bottom of the casing, are additionally provided with final drive shaft 5, the main transmission in the casing 2
Blade 6 is provided with axle 5, the final drive shaft 5 is connected with decelerator 7, and the decelerator 7 is connected with motor 8, is also included
Two are arranged at symmetrical material spraying hole 9 on 3 side wall of the feeding cylinder, the axis of the feeding cylinder 3 and the material spraying hole 9
Axis is mutually perpendicular to, and two material spraying holes 9 are connected with two Pneumatic conveyers 10 respectively, the internal diameter of the feeding cylinder 3
For 5cm to 10cm.
Such scheme is the main scheme for implementing said method of the present invention, and its principle is as follows：Coal dust mixing and blending machine as shown in Figure 1,
After according to the good coal dust of predetermined proportional arrangement and combustion adjuvant powder, by Pneumatic conveyer 10 with certain air pressure by coal dust and
In combustion adjuvant powder conveying 3 inner core of feeding cylinder, two kinds of powder, are later fallen in the 3 interior mixing that collides of feeding cylinder along with air-flow
In the middle of the stirring scope of blade.Pneumatic conveyer 10 is connected with material spraying hole 9 by delivery pipe, and the internal diameter of feeding cylinder is in 5cm
To between 10cm, compared to other larger or less 3 internal diameter sizes of feeding cylinder, both can guarantee that two kinds of powder can be in feeding cylinder 3
It is interior that mixing collision occurs, also can guarantee that the powder of enough mixing collision rifts can fall into stirring scope by feeding cylinder 3, keep away
Exempt from two kinds of powder mixing of generation and collide insufficient or blocking feeding cylinder 3 situation.The concrete set location of two material spraying holes 9 can
The axis of feeding cylinder 3 is not orthogonal to asymmetric or its axis, but asymmetric or its axis is not orthogonal to feeding cylinder 3
The powder collision effect of the ejection of material spraying hole 9 of axis is simultaneously bad, always occurs that part coal dust is not collided with combustion adjuvant powder
The situation that blade stirs scope is fallen directly into, so two are provided with along feeding cylinder axisymmetrical on 3 side wall of the feeding cylinder
The axis of material spraying hole 9 and the feeding cylinder 3 is mutually perpendicular to the axis of the material spraying hole 9.
In the middle of above-mentioned embodiment, as shown in Fig. 2 angle is usually arranged as 180 between the axis of two material spraying holes 9
Degree, but it is because that coal dust and combustion adjuvant powder are not with 1:1 ratio mixing；By between the axis of two material spraying holes 9
Angle is set to 180 °, it will usually which the situation that coal dust sprays into the material spraying hole 9 of combustion adjuvant powder occurs.It is preferred that, such as Fig. 3
It is shown, the angle between the axis of two material spraying holes 9 is set to into 120 ° to ° 150 °, injection that will be between two material spraying holes 9
Mode is set to V-shaped injection, and its mixed effect is sprayed better than traditional yi word pattern, improves the mixing of coal dust and combustion adjuvant powder
Effect.
Further, constant feeder 11 is provided with 10 feeding mouth of the Pneumatic conveyer.The coal dust that configured and
Combustion adjuvant powder is input in Pneumatic conveyer 10 into feeding mouth by constant feeder 11, is sent by Pneumatic conveyer 10
Enter material spraying hole 9.Meanwhile, the feeding port size in quantitative material feeder 11 can be adjusted, and reach and convey not within the identical time
The function of commensurability coal dust and combustion adjuvant powder.Coal dust is made to be touched with combustion adjuvant powder within the time period of feeding incessantly
Hit, reach well-mixed effect.
Further, the Pneumatic conveyer 10 is storehouse pump.Storehouse pump can be with higher air pressure pulverized coal conveying and combustion-supporting
Agent powder, is adapted to distant conveying, and operator are direct after can extracting coal dust and combustion adjuvant powder at raw material concentration
Force feed enters in blender, reduces the manpower and materials of transport, is that the manufacturing is cost-effective.
Further, the Pneumatic conveyer 10 is material envelope pump.The fed distance of material envelope pump is shorter compared to storehouse pump, gas
Pressure is relatively low, but there is no mechanical transmission mechanism part in material envelope pump, and maintenance or maintenance are simple, reliable operation.
Embodiment described above, only the preferred embodiments of the invention, when enforcement of the invention can not be limited with this
Scope, i.e., all simple equivalence changes done according to scope of the present invention patent and invention description content and modification, belong to
In the range of patent of the present invention covers.
